Is it better to use a plasma flame treatment machine or a corona machine before gluing car glass cover plates and other components?

As is well known, plasma cleaning machines are particularly suitable for surface modification of materials. In general, after low-temperature plasma cleaning treatment, the material surface will undergo a large number of physical and chemical changes, or introduce oxygen-containing polar groups, which can improve the hydrophilicity and adhesion of the material.

In general, the plasma flame treatment machine will produce different timeliness of plasma cleaning effect according to the different types of materials. Generally, it only lasts for a few minutes or months. Currently, the independently developed atmospheric plasma cleaning machine by Zhenyi Co., Ltd. has the advantages of simple process, simple modeling, fast processing speed, good treatment effect, low environmental pollution, and energy saving. It has been widely used in dry surface cleaning and activation treatment.

Plasma cleaning machine is a surface modification technology that changes the surface properties of materials through discharge. After surface treatment, the material will be combined with printing ink, paint, and adhesive to enhance the surface adhesion. If treated with an electric halo machine, the surface adhesion time can usually only be maintained for about a week, while the treatment effect of plasma cleaning machine can last for several months.

Secondly, the material requirements for the two will also be different. Generally, corona machines have specific requirements for the materials processed, while plasma cleaning machines are suitable for a wider range of materials. For example, plasma cleaning machines can be widely used on various parts of automobiles, such as car seats, instrument panels, center consoles, door interior panels, bumpers, rearview mirrors, wipers, headlights, etc., while corona machines are more commonly used in general industrial fields.

A plasma cleaning machine uses plasma to react with dirt on the surface of an object, breaking it down into smaller molecules or atoms and dissociating them from the surface to achieve thorough cleaning. It is suitable for surface cleaning of various materials. If it is necessary to clean, activate and modify the surface of the material to improve adhesion, plasma cleaning machine can be selected.

Today, let's learn together and explore the differences between plasma cleaning machines and corona machines:

1. The degree of improvement in surface adhesion between the two is different: the surface adhesion of the material treated with plasma cleaning machine can reach 52 dynes or more, while the surface adhesion of the material treated with electric motion sickness machine is usually between 32-36 dynes.

2. The application scope of the two may differ. Corona machines are usually used to process wide materials such as fabrics, films, and plastic films; Plasma cleaning machines have a wider range of applications and can handle materials with higher adhesion requirements. They can also achieve good processing results at lower temperatures and can handle silicone rubber, plastics, metal films, aluminum materials, new energy, semiconductors, and more.

3. Both have requirements for the shape of the processed object: corona machines are generally used to process thin and light products, and require that the processed object area not be too large; The plasma processing machine has no limitation on the geometric shape of the processed object, whether it is large or small, simple or complex, and can effectively process components or textiles.

4. There is also a difference in processing time between the two: the corona machine has a faster processing speed and can complete large-scale processing in a short period of time; The processing speed of plasma cleaning machines is relatively slow, but the processing effect is more precise.

5. The principle of the two is different: plasma cleaning machine: uses plasma to react with dirt on the surface of an object, decompose it into smaller molecules or atoms, and dissociate them from the surface of the object to achieve thorough cleaning. Plasma is a highly ionized gas with characteristics such as high energy, high activity, and high electron density. When plasma comes into contact with the surface of a material, it transfers energy to the surface, causing chemical bonds on the surface to break and recombine, resulting in surface modification effects. 

And motion sickness machines mainly clean the surface of objects by generating high-frequency electromagnetic fields. When a material is placed in an electric field, corona discharge occurs under the action of the electric field, causing the dirt molecules on the surface of the material to be peeled off and cleaned, while also redistributing surface electrons, resulting in surface activation effect.

The above is an analysis of the differences between corona machines and plasma treatment machines, as well as their application characteristics in automotive components!
